A measurement system of the longitudinal phase-space distribution of electrons using the combination of an optical transition radiation profile monitor and a streak camera are currently under development at ISIR, Osaka University. The energy spectrum is measured using transition radiation in a preliminary experiment. It is found that the OTR monito...

... therefore, have to broaden the acceptance angle of the photon detection system in order to make use of the transition radiation as a longitudinal phase space monitor for lower energy electrons. Figure 2 shows a schematic layout of the L-band linac. The linac is equipped with a three-stage sub-harmonic buncher (SHB) system composed of two 1/12 and one 1/6 SHBs in order to produce an intense single-bunch beam with charge up to 91 nC/bunch. ...

In order to measure the longitudinal phase-space profile of the high-brightness electron beam, we are developing the measurement system consisted of a profile monitor, a bending magnet and a streak camera. Instead of an optical transition radiation (OTR) monitor as previously considered, a Cherenkov radiator with a hydrophobic silica aerogel is used as a profile monitor. Due to the physical limitation at the installation location, we designed a simple radiator supported with a metallic mirror. The Cherenkov radiator has been designed, and it is in the process of production.
